Here you can select which temperature differences control the relay.
Subtract temperature measurement B from temperature measure-
ment A. If the measurement channel has not been taken into use or
you want to use it for something else, make the change at “Measu-
rement channel settings” in device settings.
Temperature difference (A-B), when the relay is active (ON):
The right temperature difference between the solar collector and
boiler could be, e.g., 10 °C. When the temperature of the solar collec-
tor is, e.g., 10 °C higher than the boiler temperature, the solar energy
collector’s circulating pump is controlled on.
Temperature difference (A-B) when the relay is released (OFF):
If the relay continuously becomes active and then released, the set-
ting is too small.
Relay control is activated when the difference between two tempera-
tures is large enough. Example: Solar collector/ Boiler temperature.
Relay control is activated when the valve has opened enough.
Example: At first the water in the boiler is heated using more inex-
pensive energy (e.g., an air-to-water heat pump). When the valve is
95% open a run command is given to the oil burner. The oil burner is
turned off when the position of the valve is 90%.
The relay changes its mode according to its week/ 24 hour program.
Example: Using electric heat at night for an additional heating sour-
ce. See p. 17 to create the relay’s week/24 hour program

The relay is always activated when the EH-800 controller has an
alarm that has not been acknowledged (see p. 17).
